Async Rust never left the MVP state
> It's, probably, not well-suited for things like microcontrollers, where every byte matters, but if you can afford the overhead, it's so much better than Rust async.
There is one hill I'll die on, as far as programming languages go, which is that more people should study Céu's structured synchronous concurrency model. It specifically was designed to run on microcontrollers: it compiles down to a finite state machine with very little memory overhead (a few bytes per event).
It has some limitations in terms of how its "scheduler" scales when there are many trails activated by the same event, but breaking things up into multiple asynchronous modules would likely alleviate that problem.
I'm certain a "Globally Asynchronous, Locally Synchronous" (GALS) language could have their cake and eat it too. Meaning something that combines support for a green threading model of choice for async events, with structured local reactivity a la Céu.
F'Santanna, the creator of Céu, actually has been chipping away at a new programming language called Atmos that does support the GALS paradigm. However, it's a research language that compiles to Lua 5.4. So it won't really compete with the low-level programming languages there.
